I want to get the image stream of the main pan/tilt camera of the drone, using the DJI M300 RTK, the pan/tilt camera is Zenth H20, the OSDK-ROS version number is 4.0, the development platform is MANIFOLD 2-G, Ubuntu16.04 system, The ROS version is kinetic. Through the roslaunch dji_osdk_ros dji_vehicle_node.launch command, run the protagonist point of OSDK ROS 4.0, and then start the advanced sensing function advanced_sensing_node, generate a .h264 file, you can use streameye to open the playback, but view the file information, you can not get the P frame , B frame, I frame of the video stream. How can I decode and play?

This phenomenon is not normal, it is recommended to send out the H264 video stream file to have a look.

Hello, sorry, H264 video file is too large to upload. Can you send your email?

This image is an official DJI analysis of the H264 stream. The H20 camera should be able to get P frames.
It is recommended to use Elecard StreamEye Tools or H264Visa for analysis.

Excuse me, if all P frames, how to decode and display?

The H264 stream has only P frames, indicating that it is GDR encoded and needs to be decoded using the GDR encoding format, such as you can using  JM decoder.
